You know, Sin is actually a pretty solid show. It was probably the best WCW PPV since Spring Stampede 1999, which isn't saying much since WCW PPVs had been atrocious since then, especially all of 2000. There's a real sense of enthusiasm from the talent and announcers, and most everything at least has logical booking and storytelling even if the execution isn't flawless.
The only thing that really doesn't make sense and is real WCW fuckery is the entire main event scene, where Flair is CEO and keeps booking Steiner in disadvantagous matches and Jeff Jarrett is Scott's buddy but keeps getting booked into forced situations to turn on him or otherwise cause conflict, and then there's a mystery man that keeps attacking Sid so Flair brings a mystery man himself who also beats up Sid and then it turns out the whole thing was a month(s) long ruse and Flair/Steiner were in cahoots the whole time.
The thing that really stands out is how terribly WCW handled Sid's injury. Because he needed to be pinned, they just let him hang out in the ring with his leg dangling, the "match" continued, Scott Steiner at one point actually steps on his broken leg, and it's a good 5-6 minutes before a trainer is in the ring checking on him. WWE would have immediately ended the match by either just stopping it or having Steiner quickly pin him and do the mystery surprise after.
One thing that stood out was the crowd seemed unusually hot for dying days WCW, and my suspicions were confirmed where there's a brief part in the main event where the fake crowd noise completely cuts out and the audience is as silent as you'd expect

Helms/Chavo was a stand out match, Jung Dragons vs Karagias/Knoble was pretty good, and DDP/Nash vs Palumbo/O'Haire was a really well thought out/laid out match with Nash working about as hard as you're going to see him after 1997.
